The SIB764 sensor interface board allows for a Hamamatsu S13361-3050NE-08 8 x 8 multipixel photon counter (MPPC) array to easily interface to a Vertilon PhotoniQ multichannel data acquisition system. The MPPC array is attached to the bottom side of the printed circuit board where its cathode output signals are routed directly to two sensor interface board (SIB) connectors. The SIB connectors mate to micro-coaxial cable assemblies that connect the 64 device outputs to the PhotoniQ. Bias to MPPC array is provided on a high voltage cable by the PhotoniQ where it can be enabled and configured through the PhotoniQ graphical user interface. A special current-sense tap from the bias interface circuitry is sent to a variable gain preamplifier that outputs the total charge signal measured on all 64 elements in the MPPC array. This signal is fed into a user-programmable leading edge discriminator that generates a trigger signal when an event exceeding a preset energy threshold is detected on the S13361-3050NE-08 device. The trigger output is typically connected to the trigger input on the PhotoniQ data acquisition system where it is used to initiate the collection of the energy signals from the MPPC array connected to the DAQ system’s inputs.
